◆ allDependenciesDone()

void QQmlTypeData::allDependenciesDone ( )

Called when all blobs waited for have completed.

This occurs regardless of whether they are in error, or complete state.

The default implementation does nothing.

Reimplemented from QQmlDataBlob.

Here is the caller graph for this function:

◆ completed()

void QQmlTypeData::completed ( )

overrideprotectedvirtual

Invoked on the main thread sometime after done() was called on the load thread.

You cannot modify the blobs state at all in this callback and cannot depend on the order or timeliness of these callbacks. Implementors should use this callback to notify dependencies on the main thread that the blob is done and not a lot else.

This callback is only invoked if an asynchronous load for this blob is made. An asynchronous load is one in which the Asynchronous mode is specified explicitly, or one that is implicitly delayed due to a network operation.

The default implementation does nothing.

Here is the call graph for this function:

◆ dataReceived()

void QQmlTypeData::dataReceived ( const SourceCodeData & )

overrideprotectedvirtual

Invoked when data for the blob is received.

Implementors should use this callback to determine a blob's dependencies. Within this callback you may call setError() or addDependency().

Here is the call graph for this function:

◆ done()

void QQmlTypeData::done ( )

overrideprotectedvirtual

Invoked once data has either been received or a network error occurred, and all dependencies are complete.

You can set an error in this method, but you cannot add new dependencies. Implementors should use this callback to finalize processing of data.

The default implementation does nothing.

XXX Rename processData() or some such to avoid confusion between done() (processing thread) and completed() (main thread)
